CBaseRenderer.GetCurrentSample method
[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
The GetCurrentSample method retrieves the current sample.
Syntax
virtual IMediaSample* GetCurrentSample();
Parameters
This method has no parameters.
Return value
Returns a pointer to the sample's IMediaSample interface, or NULL if no sample is available.
Remarks
Unless the method returns NULL, the method calls AddRef on the IMediaSample pointer before returning it. The caller must release the pointer. (By implication, you must assign the return value to a variable, so that you can release it later.)
